Specification of Letters Patent.

micro-FILM CARRIER.

Patented Dec. 2, 1919.

' Application filed m 22, 1919. Serial No. 298,990..

To all whom it"may concern:

Be it known thatwe, Loms F. MOKELVEY and JOHN A. BRANDENBURGER, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Photo-Film Carrier, of which the following is a specification.

It is the object of our invention to provide a photo-film carrier, which will take a plurality of films of varying length and hold them separate from each other and which will carry the films throughout the various processes of developing, fining, washing, and drying, without requiring separate handling of the films and without danger of spoiling the films.

The accompanying drawing illustrates our invention. Figure 1 is an elevation of a photo-film carrier embodying our invention, showing a number of films 1n place; Fig. 2 is a section on the line 22 of Fig. 1; and Figs. 3, 4:, and 5 are fragmentary perspective views-0f details.

A main frame is formed of two uprights 10 and a top cross-bar 11, preferably rigidly interconnected. One of the uprights 10 is provided near the top with a hole 12 for receiving one end of a removable cross-- rod 13; and the other upright 1S'pI0Y1tled. with a notch 14: having a pivoted retaining cover 15, which notch receives the other end of such cross-rod. By turning aside the cover 15, the cross-rod 13' may be readily put in place and removed. On this crossrod 13 are removably mounted a series of photo-film clips 16, conveniently by being sleeved thereupon so that they maybe put in place and removed when the cross-rod 13 is removed from the main frame. These photo-film clips are preferably of the type shown in our co-pending application Ser.

Nd. 298,989, of even filing date herewith.

- A vertically adjustable. lower cross-rod 20 has its ends fixed upon 'two sleeves 21 slidable on the uprights 10 of the main frame and arranged to bev clamped to the main frame at any desired height, as by means of clamping screws 22 in such sleeves 21. The uprights 10, the to cross-bar 11, the adjustable lo'wer cross-r0 20, and the sleeves 21 are conveniently made of rectangular metal tubing. The adjustable lower crossrod 20 is provided with a series of vertical perforations 23, in which are slidably mounted weight-rods 24 provided at their lower ends with weights 25 and at their upper ends with hooks 26, conveniently made of wire, for receiving other photo-film clips 16 in general like those mounted on the removable rod 13 but in inverted position.

Each of the films 30 which it is desired to develop has each end fastened in a photo film clip 16, and one of these photo-filmclips is slipped on the cross-rod 13 and the other on to a hook 26 substantially vertically below the film clip on the rod 13. All the films are similarly mounted, each film in its own two clips. The weights 25 stretch the films 30 between the upper and lower film clips with sufilcient tension to prevent adjacent films from engaging each other. The lower cross-rod .20 may be set at a suitable height for the average length of films being developed; the vertical movement of the rods 24: is sufficient to accommodate the usual variations in the length of the films, as is clear from Fig. 1.

When the carrier has been loaded with the desired'number of films, all of which tank, the fixing tank, the washing tank, and

the drying room; or subjected to any other treatment which is desired. This is done without requiring the films to be handled individually at all, as they are carried as a group by the frame throughout the entire series of processes. This elimination of the individual handling of the films greatly lessens the chance of spoiling the films, as well as lessening thelabor' involved. Since the films are held taut, they will not sway against each other, either when being moved or when immersed in the several solutions; this also tends to avoid spoiling the films.

We claim as our invention:

1. A photo-film carrier, comprising a frame, two cross-rods carried by said frame, said two cross-rods being relatively adjustable to vary the distance between them, and movable members mounted in-one of said cross-rods and separately tending to move away from the other cross-rod, said other cross-rod and said movable members being. arranged to detachably receive photo-film clips which may carry films between them and hold such films taut by the tendency of said movable members to'move away from said other cross-rod.

2. A photo-film carrier, comprising a.

frame, two cross-rods carried by said frame, and movable members mounted in one of said cross-rods and separately tending to move away from the other cross-rod, said other cross-rod and said movable members being arranged to receive photo-film clips which may carry films between them and hold such films taut by the tendency of said movable members to move away from said other cross-rod.

3. A photo-film carrier, comprising a frame, two cross-rods carried by said frame, and movable members mounted in one of said cross-rods and separately tending to move away from the other cross-rod, said other cross-rod and said movable members being arranged to receive photo-film clips which may carry films between them and hold such films taut by the tendency of said movable members to move away from said other cross-rod, said other cross-rod being 'removably mounted in said frame.

4:. A photo-film carrier, comprising a frame, upper and lower cross-rods carried by said frame, said two cross-rods being relatively adjustable to vary the distance between them, and a plurality of weightrods slidably mounted in said lowercrossrod and separately tending to move downward by their weight, said upper cross-rod and the upper ends of the weight-rods being arranged to receive photo-film clips which may carry films between them and frame, upper and lower cross-r weight-rods.

5. A. photo-film carrier, comprising a s carried by said frame, and a plurality of weight rods slidably mounted in said lower crossrod and separately tendin to move downward by their welght, sai up er cross-rod and the upper ends of the weig t-rods bein arranged to receive photo-film clips whic may carry films between them and hold such films taut by the weight of said weightrods. l

6. A photo-film carrier, comprising a frame, upper and lower cross-rods carried hold such films-taut by the weight of said i by said frame, and a plurality of weight rods slidably mounted in said lower crossrod and separately tending to move down- 1 ward by their weight, said upper cross-rod and the upper ends of the weight-rods being arranged to receive photo-film clips which may carry films between them and hold such films taut by the weight of said weight-rods, said upper cross-rod being removable so as to permit the mounting and dismounting of photo-film clips-thereupon.

In witness whereof, we have hereunto set our hands at Indianapolis, Indiana, this first day of May, A. D. one thousand nine hundred and nineteen.
